Cowpea (Vigna unguiculata) seeds are heavily damaged during storage by the bruchid Callosobruchus maculatus. Seeds of some Nigerian varieties showed a strong resistance to this bruchid. By utilizing biochemical and entomological techniques we were ab

Seed coat is a specialized maternal tissue that interfaces the embryo and the external environment during embryogenesis, dormancy and germination. In addition, it is the first defensive barrier against penetration by pathogens and herbivores. Here we

Since the discovery of bovine insulin in plants, much effort has been devoted to the characterization of these proteins and elucidation of their functions. We report here the isolation of a protein with similar molecular mass and same amino acid sequ

The presence of phaseolin (a vicilin-like 7S storage globulin) peptides in the seed coat of the legume Phaseolus lunatus L. (lima bean) was demonstrated by N-terminal amino acid sequencing. Utilizing an artificial seed system assay we showed that pha

Summary The gum exudate of the cashew tree (Anacardium occidentale) was shown to inhibit growth of some fungi and bacteria. The gum also prevented oviposition and reduced the number of surviving adults of the Bruchid Callosobruchus maculatus. The fee

Vicilins (7S storage proteins) found in various legume seeds have been previously shown to interfere with the germination of spores or conidia of phytopathogenic fungi and inhibit yeast growth and glucose stimulated acidification of the medium by yea

Vicilins (7S storage proteins) from cowpea (Vigna unguiculata) and other legume seeds were shown to bind to chitin, to regenerated chitin (fully acetylated chitin) and to chitosan (deacetylated chitin). Adsorbed vicilins were desorbed from these matr

Vicilins (7S storage proteins) from seeds of cowpea (Vigna unguiculata) cultivars which are susceptible or resistant to the bruchid beetle C. maculatus were purified by size-exclusion and ion-exchange chromatography. The vicilins were partially chara
